/**
* qa-traffic-preset-ab.mjs — A/B screenshot capture for preset-aware
* traffic dot styling (owner field finding 2026-07-23: NVG/FLIR/CRT
* post-FX crush the green/amber/red congestion coding).
*
* For each view, settles the live traffic layer ONCE, then for each
* post-FX style (normal / surveillance=NVG / thermal=FLIR / retro=CRT)
* drives the REAL StyleManager.setStyle path and captures:
* A — presetDots 'off' (shipped palette under that preset), and
* B — presetDots 'on' (preset-aware luminance/size encoding),
* at identical framing with the identical dot set — the kill switch
* restyles in place, no refetch, so the pair is a true A/B.
*
* Views: Mumbai Western Express Hwy (live rush window for jam coverage)
* + Austin I-35 downtown corridor (owner's usual target).
*
* Shots + per-shot layer stats land in --out
* (default qa-shots/preset-traffic, gitignored).
*
* Run: node scripts/qa-traffic-preset-ab.mjs --url http://localhost:4390
* Exits non-zero on harness failure (no live mode, zero dots, style or
* param not adopted by the layer).
